Romero and Shireman hit their first and second homers of the tourney, and doubles went to Sataraka (2), Romero, Emily Crane and Ali Aguilar.

Pitcher Erica Nunn (2-0) struck out seven, walked one, gave up two hits in her complete game.

Her Korean counterpart Jinju Lee (0-2) ended with one strikeout, no walks and 12 hits allowed in her three innings.

“The girls are doing a great job of staying in every game and attacking from the first pitch,” Team USA Head Coach Tairia Flowers said. “We’re prepared to start the playoff rounds, but there are still some things we can work on. Defensively we aren’t getting as many opportunities as we’d like, but the girls are starting to understand and read each other.”
